Liftable track bridge EMU bottom maintenance training platform

Abstract

The invention provides a lifting type railway-bridge motor-train-unit bottom practical training platform, and relates to a maintenance platform. The lifting type railway-bridge motor-train-unit bottom practical training platform comprises a railway bridge, lifting systems and pits, the railway bridge comprises a steel rail and a steel structure strut which are used for bearing a motor train unit, the steel structure strut comprises a rectangular frame and a plurality of hollow columns which are fixed to the bottom of the rectangular frame, the top of the rectangular frame is connected with the steel rail through elastic strip fasteners, the bottom of the rectangular frame is connected to the tops of the columns, and the bottoms of the columns stretch into the pits respectively; the stretching end of each lifting system is located in the corresponding column and connected to the top of an inner hole of the corresponding column. According to the lifting type railway-bridge motor-train-unit bottom practical training platform, the steel structure strut can be driven to go up and down through the lifting systems, and therefore lifting of the railway bridge and the motor train unit is achieved, inspection requirements of traveling components of the motor train unit can be met conveniently, and not only can the problem that a teacher cannot train multiple students because an existing underbody maintenance trench space at the bottom of the motor train unit is small be solved, but also production-line maintenance machinists can be trained.

Description

technical field [0001] The invention relates to an inspection and maintenance platform, in particular to a lifting-type inspection and training platform for the bottom of rail bridge EMUs. Background technique [0002] With the commissioning of the sixth major speed-up construction project of the railway, the construction of the passenger dedicated line has been fully postponed, and the passenger vehicles will be "motorized". In order to ensure the safe and stable operation of the EMU, the EMU uses the inspection warehouse for three-dimensional Platforms and track bridges have also been put into use one after another. The maintenance depot is the most important place for the use of EMUs. The main maintenance work is concentrated here. According to the requirements of the construction project for the use of EMUs, the maintenance depot is divided into three floors: the first floor is the trench , used to detect the bottom of the train; the bottom layer is a pit, and a drainage...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a liftable track bridge EMU bottom maintenance training platform to solve the problem that the existing EMU bottom maintenance car bottom ditch space is narrow and the teacher cannot train many students. In the case of convenient teaching and training, it can also meet the training work for maintenance mechanics on the production line
